For example, each the 1st liner 30a makes coniform with 4 grades of ladders, and the about 400 μ m of diameter of grid 24 sides one end extend the about 230 μ m of distolateral diameter, highly about 1-1.2mm, and the aspect ratio diameter of grid side (highly /) is 2.5-3.0.And each the 2nd liner 30b makes coniform with 3 grades of ladders, and the about 400 μ m of diameter of grid 24 sides one end extend the about 280 μ m of distolateral diameter, highly about 0.3-0.75mm, and the aspect ratio diameter of grid side (highly /) is 0.75-1.6.
As previously mentioned, the diameter of each liner perforate 28 is about 100-200 μ m, compare with the diameter of the grid side of the 1st and the 2nd liner 30a, 30b be configured to enough little.And by the 1st liner 30a and the 2nd liner 30b and liner perforate 28 are arranged and be set as one coaxially, then the 1st and the 2nd liner is connected to each other by the liner perforate, and forms one with state and the grid 24 of clamping grid 24 from the two sides.
And, the grid 24 of spacer assembly 22 as constituted above, apply the voltage of regulation by not shown power supply, when preventing cross-talk, utilize each pack perforate 26 and will emit electron beam pack that element 18 emits on required luminescent coating from the electronics of correspondence.And, the 1st and the 2nd liner 30a, 30b, by with the inner face butt of front plate 12 and backplate 10, and the atmospheric pressure load of supporting role on this two panels, and make the distance maintaining between panel become setting.
Below, the spacer assembly 22 of said structure is described and has the manufacture method of the SED of this spacer assembly.
Making the occasion of spacer assembly 22, at first as shown in Figure 4, preparing the grid 24 of given size and have the 1st and the 2nd mould 32,33 with the rectangle of grid approximate same size.On grid 24, be pre-formed pack perforate 26 and liner perforate 28, be covered with for example melanism film or the oxide-film that constitutes by granular oxide the outside is whole.
And the 1st and the 2nd mould 32,33 forms a plurality of open-works 34 corresponding with the liner perforate 28 of grid 24 respectively.At this, as shown in Figure 5, the 1st mould 32 is with multi-disc, for example 4 sheet metal 32a, 32b, 32c, 32d are laminated.
In detail, each sheet metal constitutes with the Ferrious material plate of thickness 0.25-0.3mm, and forms cone shape a plurality of open-work respectively.And the open-work of sheet metal 32a, 32b, 32c, each self-forming of 32d has the different diameter of open-work that forms with other sheet metals.For example, forming cone shape open-work 34a that maximum gauge is 400 μ m on the sheet metal 32a, forming cone shape open-work 34b that maximum gauge is 350 μ m on the sheet metal 32b, be the cone shape open-work 34d of 240 μ m respectively in that to form maximum gauge on the sheet metal 32c be the cone shape open-work 34c of 295 μ m, form maximum gauge on sheet metal 32d.These open-works 34a to 34d utilizes etching or laser radiation to form.
And, these 4 sheet metal 32a, 32b, 32c, 32d, with open- work 34a, 34b, 34c, the 34d state of arranged in co-axial alignment and stacked roughly, and connected diffusely mutually in a vacuum or in the reducing atmosphere with the state of sequentially arranging from the big open-work of diameter.Thus, integral body forms the 1st mould 32 of 1.0-1.2mm, and each open-work 34 has coniform inner peripheral surface regulation, the band ladder by 4 open- work 34a, 34b, 34c, 34d are aimed at.
In addition, the 2nd mould 33 is also the same with the 1st mould 32, for example, 3 sheet metals is constituted stackedly, and each open-work 34 has coniform inner peripheral surface regulation, the band ladder by 3 coniform open-works.
In addition, the outside of the 1st and the 2nd mould 32,33 also comprises being covered the inner peripheral surface of each open-work 34 by superficial layer.The relative aftermentioned liner of this superficial layer forms material and has fissility, and has an oxidative resistance, for example, utilizing the eutectoid of the refractory metal of the atomic eutectoid plating of Ni-P and polytetrafluoroethylene, oxide, nitride, carbide or Ni-P and W, Mo, Re etc. to plate forms.
In the manufacturing process of spacer assembly, as shown in Figure 6A, the 1st mould 32 is close on the 1st surperficial 24a of grid and is made the larger diameter side of each open-work 34 be positioned at grid 24 sides, and be configured to make each open-work to be positioned to the state of arranging with the liner perforate 28 of grid.Equally, the 2nd mould 33 is close on the 2nd surperficial 24b of grid and is made the larger diameter side of each open-work be positioned at grid 24 sides, and be configured to make each open-work to be positioned to the state of arranging with the liner perforate 28 of grid.And the clamping plate that these the 2nd moulds 32, grid 24 and the 2nd mould 33 usefulness are not shown etc. are fastened to each other.
Below, shown in Fig. 6 B, use squeegee 36, for example, the liner of supplying with paste-like from the exterior side of the 1st mould 32 forms material 40, and liner is formed the material filling in the open-work 34 of the liner perforate 28 of the open-work 34 of the 1st mould 32, grid 24 and the 2nd mould 33.The unnecessary liner that drains to the exterior side of the 2nd mould 33 forms agent 40, scrapes off with squeegee 38.
Form material 40 as liner, use and contain the bonding agent (organic principle) of UV cured type and the glass paste of glass filler at least.
Then, shown in Fig. 6 C, ultraviolet ray (UV) is formed material 40 from the exterior side of the 1st and the 2nd mould to the liner of filling as radiation shine, make liner form material UV sclerosis.Carry out the UV sclerosis by making liner form material 40 in this wise, thereby the close property that makes liner form the relative grid 24 of material is higher than the close property that liner forms material the relative the 1st and the 2nd mould 32,33.
Then, shown in Fig. 7 A, under the state that the 1st and the 2nd mould 32,33 is close on the grid 24, they are heat-treated in heating furnace, after making bonding agent form material 40 interior effusions, baked liner with about 500-550 ℃, 30 minutes-1 hour and form material from liner.Thus, the 1st and the 2nd liner 30a, the 30b of formation and grid 24 one.
After this, the 1st and the 2nd mould 32,33 and grid 24 be cooled to set point of temperature after, shown in Fig. 7 B, the 1st and the 2nd mould is peeled off from grid 24.Thus, finish spacer assembly 22.
Using the occasion of making SED as the spacer assembly 22 of above-mentioned manufacturing, setting in advance electronics emits element 18 and prepares the backplate 10 that connects sidewall 14 in advance and be provided with phosphor screen 16 and the front plate 12 of metal gasket 17, and, under spacer assembly 22 is positioned state on the backplate 10, this backplate and front plate 12 are configured in the vacuum chamber, in with vacuum chamber, make under the state of vacuum exhaust, front plate 12 is connected with backplate 10 by sidewall 14.Thus, make SED with spacer assembly 22.
Spacer assembly 22 and SED according to said structure with this spacer assembly 22, each insert integral ground has a plurality of end differences stacked to elongated end and that diameter diminishes gradually, and each end difference makes to extending the coniform of distolateral taper, make the coniform of band ladder as a whole, that is, make roughly frustoconical shape with ladder.Therefore, utilize mould molding a plurality of insert integrals ground can be done on grid, can obtain the spacer assembly and the SED that can make easily.
And, according to the manufacture method of above-mentioned spacer assembly, by under the state on the grid, baking liner and form material, then can once a plurality of liners be done on the assigned position on the grid utilizing mould liner to be formed material configuration.Therefore, can make spacer assembly easily, can reduce manufacturing cost and improve and make efficient with a plurality of fine liners.
And, by baking liner being formed under the state of material filling in the open-work of mould, then make liner form that material is defeated and dispersed to come baking Shi Buhui, can form the high liner of aspect ratio easily with enough height.
In addition, in this example, form material as liner, use contains the bonding agent of UV cured type and the glass paste of glass filler, before baking, irradiation ultraviolet radiation makes liner form hardened material, and by utilizing by the grid of oxide-film lining with by the mould of the superficial layer lining with oxidative resistance, and the close property that can make liner form the relative grid of material is higher than the close property of relative mould.Thus, in baking afterwards, the stripping process, the pad attach that can prevent to form is in die side, and can form the liner with the grid one reliably.
In addition, according to this example, each mould is stacked the forming of multi-disc sheet metal that will form open-work respectively.Usually, the diameter that liner be formed usefulness be that the fine open-work of hundreds of μ m forms on the metallic plate of the above thickness of about 1mm is unusual difficulty.To this, if the thick sheet metal of about 0.1-0.3mm utilizes etching, laser radiation etc., and can more easily form fine open-work.Therefore,, undertaken stackedly by the multi-disc sheet metal that will form open-work, and can easily obtain to have the mould of the open-work of desired height as this example.
And, in above-mentioned mould, be formed at open-work on each sheet metal and make coniformly, and the every sheet metal of its diameter is inequality.Therefore, with these multi-disc sheet metals when stacked,, also can obtain to make the open-work of each sheet metal to be communicated with and to have the mould of required open-work each other reliably even when producing a position deviation.In addition, above-mentioned mould is owing to form the superficial layer lining that material has fissility with relative liner, so liner formation material is difficult to can be used for the manufacturing of spacer assembly repeatedly in the open-work attached to mould.
Below, the SED and the manufacture method thereof of spacer assembly with the 2nd example of the present invention described.
As shown in Figure 8, according to the 2nd example, the grid 24 of spacer assembly 22 does not have the liner perforate, and the 1st and the 2nd liner 30a, 30b independently and with grid 24 form one respectively.
That is to say, a plurality of the 1st liner 30a, upright being located between the pack perforate 26 on the 1st surperficial 24a of grid 24, and by the black colorant layer of metal gasket 17 and phosphor screen 16 with the inner face butt of front plate 12.And, a plurality of the 2nd liner 30b, upright being located between the pack perforate 26 on the 2nd surperficial 24b of grid 24, with the inner face butt of backplate 10, and respectively with the 1st liner 33a alignment arrangements.Other structures are identical with SED in aforesaid the 1st example, so identical part is put on identical reference marks and omitted its detailed description.
In the occasion of the spacer assembly 22 of making said structure, at first, shown in Fig. 9 A, the 1st mould 32 is close on the 1st surperficial 24a of grid and is made the larger diameter side of each open-work 34 be positioned at grid 24 sides, and be positioned to make each open-work between the pack perforate 26 of grid.Then, use squeegee 36, the liner of supplying with paste-like from the exterior side of the 1st mould 32 forms material 40, and liner is formed the material filling in the open-work 34 of the 1st mould 32.And liner forms material 40 and uses the structure identical with aforementioned example with the 1st mould 32.
Below, shown in Fig. 9 B, the exterior side of ultraviolet ray (UV) from the 1st mould 32 shone the liner formation material 40 of filling in open-work 34, make liner form material UV sclerosis.Thus, the close property that makes liner form material 40 relative grids 24 forms the close property height of relative the 1st mould 32 of material than liner.
After this, shown in Figure 10 A, under the state that grid 24 and the 1st mould 32 is keep being close to, the 2nd mould 33 is close to is made the larger diameter side of each open-work 34 be positioned at grid 24 sides on the 2nd surperficial 24b of grid, and be positioned to each open-work between the pack perforate 26 of grid.And the clamping plate that these the 1st moulds 32, grid 24 and the 2nd mould 33 usefulness are not shown etc. are fixing mutually.
Then, use squeegee 36, the liner of supplying with paste-like from the exterior side of the 2nd mould 33 forms material 40, and liner is formed the material filling in the open-work 34 of the 2nd mould 33.In addition, the 2nd mould uses the mould identical with aforesaid example.
After this, shown in Figure 10 B, the exterior side of ultraviolet ray from the 2nd mould 33 shone the liner formation material 40 of filling in open-work 34, make liner form material UV sclerosis.Thus, make liner form material 40 forms relative the 2nd mould 32 of material than liner with respect to the close property of grid 24 close property height.
Then, shown in Figure 10 C, under the state that the 1st and the 2nd mould 32,33 is close on the grid 24, they are heat-treated in heating furnace, make bonding agent after liner formation material 40 interior effusions, baked liner with about 500-550 ℃, 30 minutes-1 hour and form material.Thus, the 1st and the 2nd liner 30a, the 30b of formation and grid 24 one.
And, after the 1st and the 2nd mould 32,33 and grid 24 are cooled to set point of temperature, peel off by peel off the 1st and the 2nd mould 32,33 from grid 24, finish spacer assembly 22.And, have the manufacturing of SED of the spacer assembly 22 of said structure, use with the same operation of aforementioned example and carry out.
Even in the 2nd example of above-mentioned formation, also can obtain the action effect same with aforementioned example.
In addition, in the above-mentioned the 1st and the 2nd example, though spacer assembly makes the structure that has the 1st and the 2nd liner on the two sides of grid 24 respectively integratedly, the 3rd example that also can be as shown in figure 11 is such, makes the structure that liner only is set on a side surface of grid.
That is to say that according to the 3rd example, spacer assembly 22 has a plurality of the 1st liner 30a on grid 24 and upright integratedly the 1st surperficial 24a that is located at grid.These the 1st liners 30a is upright to be located between the pack perforate 26, by the black colorant layer of metal gasket 17 and phosphor screen 16 with the inner face butt of front plate 12.
In addition, overleaf on the inner face of plate 10, uprightly integratedly be provided with a plurality of the 2nd liner 30b, be arranged in respectively on the position relative with the 1st liner 30a and with the 2nd surperficial 24b butt of grid 24.
And, the 1st and the 2nd liner 30a, 30b, identical with aforesaid example, form the cone shape of the band ladder of taper respectively to elongated end, that is, form band ladder frustoconical shape.Again, another structure of SED is identical with aforesaid example, puts on identical reference marks and omits its detailed explanation for identical part.
In the 3rd example, the method that spacer assembly 22 utilizes and aforesaid the 2nd example is same is made.But omit the manufacturing process of the 2nd liner.
And in the 3rd example, a plurality of the 2nd liner 30b constitute another spacer assembly 22 with the next substrate that constitutes backplate 10.And this spacer assembly 22 is also used with the same method of the 2nd example and is made.
That is to say, replace grid and on the surface of the backplate 10 that constitutes by glass substrate, aforesaid the 2nd mould 33 is close to, is positioned on the position of regulation, so that the larger diameter side of each open-work 34 is positioned at backplate one side.Then, the liner of supplying with paste-like from the exterior side of the 2nd mould 33 forms material, and liner is formed in the open-work 34 that material is filled in the 2nd mould.Liner forms material and uses and aforementioned example identical materials.
Then, ultraviolet irradiation is formed material and makes liner form material UV sclerosis at the liner of filling in open-work.Thus, the close property that makes liner form the relative backplate 10 of material forms the close property height of relative the 2nd mould 33 of material than liner.At this, constitute the glass substrate of backplate 10, owing to himself be oxide, so also can not even do not form oxide-film on overleaf outside the plate.
After this, under the state that the 2nd mould 33 is close on the backplate 10, they are heat-treated in heating furnace, with bonding agent from liner form overflow in the material after, bake liner and form material.Thus, the 2nd liner 30b of formation and backplate 10 one.
And, after the 2nd mould 33 and backplate 10 are cooled to set point of temperature, by the 2nd mould 33 being peeled off, finished the spacer assembly 22 that has backplate 10 and the 2nd liner 30b integratedly.
Even in the 3rd example of above-mentioned formation, also can obtain and the same action effect of aforesaid other example.
Below, the SED of the 4th example of the present invention is described.As shown in figure 12, constituting between the front plate 12 and backplate 10 of vacuum casting 15, in order to prevent to set spacer assembly described later 22 at the paradoxical discharge between this two panels with the battery lead plate that is connected with the current potential of stipulating.And front plate 12 and backplate 10 are supported by these spacer assembly 22 relative atmospheric pressure, and keep the predetermined distance between panel, for example interval of 1.6mm.
Front plate 12 has the phosphor screen 16 on insulated substrate that is made of alkali-free glass and the inner face that is formed on this insulated substrate.Phosphor screen 16 has: have the characteristics of luminescence of red (R), blue (B), green (G) respectively and with the luminescent coating 13 of the striated of 0.6mm spacing configuration; Be configured between the fluorescence coating body layer 13, be used to improve the light shield layer 11 of band shape of the ratio of contrast.
In addition, on phosphor screen 16, form the conductive membrane layer 19 that constitutes by aluminium or its alloy, on this conductive membrane layer 19, form the evaporation gettering layer 21 that constitutes by barium (Ba) again.The conductive membrane layer 19 of such front plate 12 has the function of positive electrode.And, evaporation gettering layer 21, before in vacuum chamber, front plate 12 and backplate 10 being fitted, by in vacuum chamber, forming by the evaporation gettering material, and carry out in that series of processes from the evaporation of getter material to sealing is not exposed under the state that atmosphere ground keeps vacuum, and can obtain high performance evaporation gettering layer 21.
As Figure 12 and shown in Figure 14, backplate 10 has the insulated substrate that is made of alkali-free glass, on the inner face of this insulated substrate, be provided with the many scan electrodes 23 and the signal electrode 25 of rectangular configuration, and near the cross part of this scan electrode 23 and signal electrode 25, be respectively equipped with from scan electrode and signal electrode and extend the control electrode 27 and the emitter 29 of configuration.
Control electrode 27 and emitter 29 leave predetermined distance ground for example 50 μ m and relative configuration, and, between this control electrode 27 and 29, though not shown, but relatively dispose graphite film with interval, constitute surface conductive type electronics thus and emit element 18 with 5 μ m.And, on each scan electrode 23, be formed with diaphragm 31.
Between the front plate 12 of above-mentioned formation and backplate 10, be provided with spacer assembly 22, relatively atmospheric pressure supporting front plate and backplate.Below, describe this spacer assembly 22 in detail.
As Figure 12 and shown in Figure 14, spacer assembly 22 has the battery lead plate 42 that disposes in order to prevent paradoxical discharge between front plate 12 and backplate 10.This battery lead plate 42 is made with the Fe-Ni alloys of thick 0.1mm, and oxidation processes is carried out on its surface.The thickness of slab of battery lead plate 42 is though also according to its size, if make and the effective viewing area corresponding size of diagonal-size more than 20 inches, then in order to ensure required intensity, be preferably formed as the thickness that is about 0.1-0.25mm.
In addition, in order to ensure property easy to manufacture, though also consider a plurality of battery lead plates 42 that form with cutting apart, because the harmful effect that demonstration is brought in its boundary portion, so preferably use large-scale battery lead plate with effective viewing area 3 corresponding sizes within the bounds of possibility.
Battery lead plate 42 is configured to parallel with this two panels between front plate 12 and backplate 10.And, on battery lead plate 42, with surface conductive type electronics emit element 18 practise physiognomy form over the ground a plurality of.Make the perforate 26 of emitting the rectangle of 250 μ m * 180 μ m that wire harnesses that element 18 emits sees through usefulness from surface conductive type electronics respectively.And, on battery lead plate 42, be formed with the liner perforate 28 that connects a plurality of circles that the described later the 1st and the 2nd liner uses.
Battery lead plate 42 has 1st surface relative with front plate 12 and 2nd surface relative with backplate 10.Formed a plurality of the 1st liner 30a in the 1st face side and battery lead plate 42, and, formed a plurality of the 2nd liner 30b in the 2nd face side and battery lead plate 42.And the 1st liner 30a utilizes the connecting portion 52 that is configured in the liner perforate 28 that is formed on the battery lead plate 42 to be connected with the 2nd liner 30b.In this example, 2 the 1st liner 30a are connected with 1 the 2nd liner 30b by connecting portion 52 respectively.
As Figure 12 to shown in Figure 14, the 2nd liner 30b, to emit element 18 corresponding and be configured on the scan electrode 23 by diaphragm 31 with each surface conductive type electronics, and extend along the distribution direction.The cross section of each the 2nd liner 30b forms oblong, length L 1 along the distribution direction of battery lead plate 42 sides is 0.4mm, along the length L 2 with distribution direction orthogonal direction is 500 μ m, along the length L 1 of the distribution direction of backplate 10 sides ' be 0.35mm, along with the length L 2 of distribution direction orthogonal direction ' be 400 μ m, and height h1 forms 0.5mm respectively.
In addition, the 1st liner 30a, relative 1 the 2nd liner 30b respectively is provided with 2.Each the 1st liner 30a forms and has the cylindric of some taperings, and the diameter phi 1 of the end of plate 42 sides is 320 μ m, and the diameter phi 2 of the end of front plate 12 sides is 230 μ m, and its height h2 forms 1.0mm respectively.
That is to say, in the 4th example, form enough greatly relative the 2nd liner 30b of the aspect ratio of the 1st liner 30a length ratio of the major cross-sectional axis direction of battery lead plate 42 sides (height with).And, the height of the 2nd liner 30b form the 1st liner 30a height pact half.
And 2 the 1st adjacent liner 30a pass through the liner perforate 28 of battery lead plate 42 respectively, promptly are connected with 1 the 2nd liner 30b by connecting portion 52, constitute one with the 2nd liner 30b and battery lead plate 42.The diameter of this connecting portion 52 and liner perforate 28 forms the diameter phi 1 less than battery lead plate 42 sides of the 1st liner 30a.
Under the spacer assembly 22 that will constitute like this was provided in state in the vacuum casting 15, battery lead plate 42 was relative abreast with front plate 12 and backplate 10, the paradoxical discharge between the panel that prevents from simultaneously to be connected with the regulation current potential.And; each the 2nd liner 30b by diaphragm 31 and scan electrode 23 and with backplate 10 butts, each the 1st liner 30a, by evaporation gettering layer 21, conductive membrane layer 19 and phosphor screen 16 with front plate 12 butts; thus, atmospheric pressure supports front plate 12 and backplate 10 relatively.
SED according to above-mentioned formation, the 2nd liner 30b of spacer assembly 22, owing to emit element 18 and its height less than 0.5mm, so no matter be disposed on the enough big area the charged track that also is difficult to influence the electronics line of the 2nd liner 30b along scan electrode 23 near being configured in surface conductive type electronics.
